Ronak Jain 578f468ac0 feat(plat/xilinx/zynqmp): add support for runtime feature config
Add support for runtime feature configuration which are running on the
 firmware. Add new IOCTL IDs like IOCTL_SET_FEATURE_CONFIG and
 IOCTL_GET_FEATURE_CONFIG for configuring the features.

Venkatesh Yadav Abbarapu 62f9134de0 revert(plat/xilinx): add timeout while waiting for IPI Ack
This reverts commit 4d9b9b2352.

Timeout in IPI ack was added for functional safety reason.
Functional safety is not criteria for ATF. However, this
creates issues for APIs that take long or non-deterministic
duration like FPGA load. So revert this patch for now to fix
FPGA loading issue. Need to add support for non-blocking API
for FPGA loading with callback when API completes.

Venkatesh Yadav Abbarapu 302b4dfb8f feat(plat/versal): add support for SLS mitigation
This patch adds the option HARDEN_SLS_ALL that can be used to enable
the -mharden-sls=all, which mitigates the straight-line speculation
vulnerability. Enable this by adding the option HARDEN_SLS_ALL=1,
default this will be disabled.

Abhyuday Godhasara fa58171534 fix(plat/xilinx/versal): use sync method for blocking calls
All API calls except non-blocking should wait for
IPI response and read buffer to check return status
from firmware. Some of API calls are not reading
status from IPI payload data. Use sync method which
reads actual return status from IPI payload.

Michal Simek 0a8143dd63 feat(plat/zynqmp): extend DT description by TF-A
In case of TF-A running out of DDR there is a need to reserved
memory to let other SW know that none can't use this memory. HW
wise this region can be (and should be) also protected by
protection unit XMPU. This is the first step to add reserved
memory location to DT.

DT address corresponds with default address in U-Boot and also
default address in Xilinx BSPs.

Code is valid only when TF-A runs out of DDR. When it runs out
of OCM there is no need to reseve anything because OCM is hidden
to OS.

Jan Kiszka 4143268a5c feat(plat/zynqmp): add SDEI support
Add basic SDEI support, implementing the software event 0 only for now.
This already allows hypervisors like Jailhouse to use SDEI for internal
signaling while passing the GICC through to the guest (see also IMX8).

With SDEI on, we overrun the SRAM and need to stay in DRAM. So keep SDEI
off by default.

Ravi Patel c8f6253683 zynqmp: pm: Update flags in common clk divisor node
Current implementation doesn't support change of div1 value if clk
has 2 divisor because div1 clk is the parent of the div2 clk and div2
clk does not have SET_RATE_PARENT flag.
This causes div1 value to be fixed and only value of div2 will be
adjusted according to required clock rate.

Example:
 Consider a case of nand_ref clock which has 2 divisor and 1 mux.
 The frequency of mux clock is 1500MHz and default value of div1 and
 div2 is 15 and 1 respectively. So the final clock will be of 100MHz.
 When driver requests 80MHz for nand_ref clock, clock framework will
 adjust the div2 value to 1 (setting div2 value 2 results final clock
 to 50MHz which is more inaccurate compare to 100Mhz) which results
 final clock to 100MHz.
 Ideally the value of div1 and div2 should be updated to 19 and 1
 respectively so that final clock goes to around 78MHz.

This patch fixes above problem by allowing change in div1 value.
